DESCALE AIR quickly and effectively dissolves and removes boiler scales, iron oxides, corrosion, algae, and other mineral deposits in refrigeration and AC systems. It does not contain chlorinated acids, making it very safe for all types of metals, seals, o-rings. It can remain in the cleaned system up to 24 hours. It is a non-toxic and non-flammable product with a corrosion inhibitor to protect the cleaned metal surfaces. A pH indicator ensures effective use of the agent during cleaning or descaling. DESCALE AIR is also an important prevention agent against the growth of Legionella pneumophila bacteria, which is facilitated by rust and scale.
